They begin today on the East Coast of the United States.
Shane Lowry aims to continue the feel good factor from Offaly's All-Ireland win in the FedEx Cup Playoffs today.
He begins his first round at The Northern Trust in Liberty National Golf Club in New Jersey.
The Clara man plays alongside Martin Laird and Canadian Mackenzie Hughes from 5.10pm Irish time.
The playoffs are the culmination of the PGA Tour season in which the top 125 ranked players are invited to the first tournament of a three week series.
The top 70 finishers in New Jersey will then advance to play in the BMW Championship in seven days time, with the top 30 there making the cut for the final weekend in Atlanta.
Lowry currently sits ranked 66th heading into the event.
The overall winner of the PGA Playoff series nets a cool $15,000,000.
